Chemistry Question on d -and f -Block Elements
The transition elements have a general electronic configuration.
A
ns2np6nd1−10
B
(n−1)d1−10,ns0−2,np0−6
C
(n−1)d1−10,ns1−2
D
nd1−10ns2
Answer
(n−1)d1−10,ns1−2
Explanation
Solution
In the transition elements, the d-orbitals are successively filled. The general electronic configuration of d-block is \hspace5mm (n-1)d^{1-10}ns^{1-2} Where (n - 1) stands for inner shell and d-orbitals may have one to ten electrons and the s-orbital of the outermost shell (n) may have one or two electrons.
